l Claim.

My invention relates to improvements in disinfectng and deodorizing devices for toilet equipment of the type embodying a flushing tank.

The primary object of the invention is to provide means of simple form and inexpensive construction adapted for easy, quick attachment to the usual ushing tank of present` day toilet equipment, and to feed a disinfecting and deodorizing liquid drop by drop into the usual overflow pipe of the flushing tank to nd its way through said overflow pipe into the toilet rbowl and thereby act as a disinfectant and deodorizing medium in said bowl. f

Other and subordinate objects are also comprehended by my invention, all of which, together with the precise nature of my improvements, will be readily understood when the succeeding description and claim are readwith reference to the drawingsaccompanying and forming part of this specification.` i

In said drawings: V

Figure 6 isa view in longitudinal section of the valve of the liquid feed nozzle of Figure 5,

Figure 7 is a fragmentary view in end elevation of the modified embodiment of liquid supplying receptacle,

Figure 8 isr a detail view in section taken on the line 8-8 of Figure 4,

Figure 9 is a fr-agmentary detail view in horlzontal section of one of the keepers,

Figure 10 is a detail view in plan of one of the supports.

Reference being had to the drawings by numerals, and first to Figures 1, 2 and 3, my improved disinfecting and deodorizing device comprises, in the preferred embodiment thereof, a shallow, generally rectangular liquid s-upplying receptacle I of a width adapting the same to fit in the top of the usual flushing tank 2, and of a length substantially equal to half the lengthv of said tank. The liquid supplying receptacle I is closed, with the exception of a suitable filler neck 3 in the center and top of said receptacle, and a small aperture in said top adjacent one end of the receptacle. A hollow boss 5 is suitably Xed to the top of the receptacle in communication with said aperture, designated 4, said boss having an internally threaded bore 6 therein.

The liquid supplying receptacle I is provided on the top thereof with means for suspending the same from the edges of the flushing tank 2, said means comprising a pair of side tabs I and an end tab 8 and which are of bendable material and adapted to be bent so as to hook over adjacent top edgesl of the tank 2, as shown in Figure 1. As will be seen in Figure 1, the described tabs l, 8 provide for suspending the liquid supplying receptacle I in the top of the iiushing tank 2 in a hidden position and so that said receptacle may be covered by the usual cover, not shown, for said tank. Aswill also be seen in said gure, the liquid supplying tank I, when thus suspended, presents the boss-equipped end thereof adjacent the usual overflow pipe 9 of the flushing tank 2 with said end above said pipe.

A liquid feed nozzle, in the form of a gooseneck pipe Ill, depends from the boss 5 with one end threaded into the bore B and secured therein by a lock nut Il. The other end of the pipe I0 terminates in a flat portion I2 vertically aligned with the overflow pipe 9 and terminating at substantially the level of the upper end of said pipe 9. A wick I3 extends through said'pipe I0 with an outer end portion I4 fitted tightly in the attened end portion I2 of the pipe IIJ, the remainder ofthe' wicktting loosely in the remainder `of said pipe I0 and depending out of the boss 5 into the liquid supplying receptacle I through the aperture 4.

Referring now to the operation of the described embodiment of my invention, the liquid supplying tank I is designed to be filled with a, suitable disinfecting and deodorizing liquid, not shown, and which is fed through the wick I3, by capillary attraction, through the described nozzle or pipe I0 into the overflow pipe 9 drop by drop. From the overflow pipe 9, the liquid finds its way into the water discharge line I5 of the flushing tank 2 each time the usual flushing valve I6 is operated. Also, the overflow pipe communicating at its lower end with the water discharge pipe I5, in the usual manner, well understood, the disinfectlng and deodorizing liquid drains into said pipe I5 even when the flushing valve I6 is closed.

In the modified embodiment of the invention shown in Figures 4 to 10, the liquid supplying tank I 'I is provided with an end discharge nipple I8 adjacent the bottom of said receptacle and, as best shown in Figure 5, with a gravity feed nozzle including a goose-neck pipe I9 having an upper end attached to the nipple I8 by a coupling 20, and a feed control discharge valve 2| at its lower depending end vertically aligned with the overow pipe 9 of the flushing tank.

The valve 2| comprises a downwardly opening, tubular body 22 provided with a. knurled finger grip part 23 :and a reduced upper and threaded nipple 24 by means of which and a coupling 25 said body is attached to the lower end of the goose-neck pipe I9. A valve core 26 is threaded upwardly into the body 22 to depend therefrom and is provided with an upper tapered end 21 adapted to seat in the lower end of the nipple 24 and close the valve. A nut-like head 28 is providedy on the lower end of the core 26' for turning the same, and a coil spring 29 circumposed on s'aid core between the body 22 and said head 28 functions to lock said core yieldingly against turning. A port 30 extending laterally into the core 26 within the body 22 and then axially of said core through the headed end thereof provides for the discharge of liquid through the valve when the core 26 is turned to unseat the end 28 of the core, as will be clear. The core 26 is reduced in size from the port 30 to its upper end to provide a clearance for the escape of liquid through the body 22v into said port.

' For suspending the liquid supplying receptacle Il in the sam-e manner as the receptacle I, said receptacle I1' is provided on the top thereof adjacent the nipple-equipped end of the same with a pair of side, transversely extending, hollow keeper bosses 3I, and at the end thereof opposite to the nipple-equipped end with a single longitudinally extending similar keeper boss 32. Bar-like supports 33 are fitted in the keeper bosses 3I to extend. out of the same from the sides of the receptacle II and' are equipped with upwardly offset outer ends 34 designed to flt over the side edgesv of a flushing tank such as shown in Figure 1. A similar support 35 is provided in the boss 32 to t over the end of the tank. Tabs 36 on said support bent up therefrom over the ends of the keeper bosses 3I, 32, as the case may be, secure the supports in their respective keepe bosses. l

l As will be seen, in the modified embodiment of the invention described, the liquid, not shown, in the liquid. supplying tank' I1 is fed by gravity through the goose-neck pipe I9 and valve 2| into the overflow pipe 22 and the feed may be regulated, by turning the core 26 so that a drop-bydrop feed may be attained.

The foregoing will, it is believed, sufce to impart a clear understanding of my invention without further explanation.

Manifestly, the invention, as described, is susceptible of .modification without departing from the inventive concept, and right is herein reserved to such modifications as fall within the scope of the appended claim.

What I claim is A device of the class described for use in a ush tank having an upstanding overflow pipe discharging into a ushing line, said device comprising a supply tank for a deodorizing and disinfecting liquid, a gravity feed pipe depending from said supply tank, means on said supply tank adapted for suspending the same from the upper edge of the flush tank with the feed pipe vertically aligned with the overflow pipe, and a dropper valve on. the lower end of the feed pipe for continuously discharging liquid therefrom drop by drop, said valve including a body having an elongated vertically disposed core with an axial port for discharge of said liquid from the lower end thereof and being settable longitudinally in the body to vary the rate of discharge from said port, said port having a lateral inlet end within said body, and said core having an inner end in said body reduced from said inlet end of the port for passage of liquid to said port, and spring means tensioning said core against movement out of set position.
